I am running Fedora22 Workstation. How do I assign a keyboard shortcut of my choice, say, Alt-Ctl-L/ Alt-Ctl-U to adjust screen brightness?

Settings -> Keyboard -> Shortcuts does not carry any item for this.

I'm not sure if you even can do that on the desktop. If you're using laptop and don't want to use your Fn key + whatever key changes your backlight level you could install program called xbacklight.x86_64 and map command xbacklight -inc 5 for increasing backlight level by 5% and xbacklight -dec 5 for decreasing backlight by 5%.

Unfortunately "I cannot confirm or deny that this will work on any setup", though it works on my particular laptop. :-)

can you give us noobs a "quick and dirty" walkthrough for how you did it? I don't know how to "map command xbackbacklight -inc 5"

You can map that command within Settings -> Keyboard -> Shortcuts :-) Create custom shortcuts, under command place that command and map shortcut afterwards.
